"IDACORP continued its steady financial performance, achieving its twelfth straight year of growth in earnings per share," said Darrel Anderson, IDACORP's President and Chief Executive Officer. "The record fourth quarter and full-year results were driven by strong economic activity in Idaho Power's service area, along with solid performance across IDACORP's other subsidiaries. New customers continue to move into the service area, and this customer growth, along with effective cost management, again enabled Idaho Power to preserve tax credits to support future earnings.

"In addition to the unprecedented financial results, Idaho Power achieved its best ever employee safety record and its highest ever residential customer satisfaction score. Idaho Power also continued its strong performance in system reliability, only slightly behind 2018's record result," added Anderson.

IDACORP is initiating its full year 2020 earnings guidance in the range of $4.45 to $4.65 per diluted share, and Idaho Power does not expect to use any of the tax credits available under the Idaho regulatory stipulation. This earnings guidance assumes normal weather conditions.

Net Income - Fourth Quarter 2019

IDACORP's net income increased $21.0 million for the fourth quarter of 2019 compared with the fourth quarter of 2018, primarily due to higher net income at Idaho Power. Customer growth increased operating income by $4.7 million in the fourth quarter of 2019 compared with the fourth quarter of 2018, as the number of Idaho Power customers grew by 2.5 percent during the twelve months ended December 31, 2019. Lower sales volumes on a per-customer basis decreased operating income by $2.1 million in the fourth quarter of 2019 compared with the fourth quarter of 2018, primarily related to lower per-customer industrial sales.

The net increase in retail revenues per MWh increased operating income by $1.8 million in the fourth quarter of 2019 compared with the fourth quarter of 2018. This increase was largely driven by changes in the customer sales mix, as volumes sold to residential customers in the fourth quarter of 2019 made up a greater portion of the customer sales mix compared with the fourth quarter of 2018. Residential customers generally pay a higher per-MWh rate than other customers.

Other O&M expenses were $1.7 million lower in the fourth quarter of 2019 compared with the fourth quarter of 2018, as Idaho Power's continued focus on managing other O&M expenses resulted in lower expenses across a number of areas.

Under the Idaho regulatory settlement stipulation approved in October 2014, Idaho Power recorded a $3.5 million provision against revenues for sharing of earnings with customers during the fourth quarter of 2018, based on its estimate of full-year 2018 return on year-end equity in the Idaho jurisdiction (Idaho ROE). Based on its 2019 Idaho ROE, Idaho Power recorded no additional accumulated deferred investment tax credit (ADITC) amortization or provision against current revenues for sharing of earnings with customers in 2019 under the Idaho regulatory settlement stipulation approved in October 2014.

Overall, Idaho Power operating income increased by $6.6 million for the fourth quarter of 2019 compared with the fourth quarter of 2018.

Non-operating income and expenses, net, improved $9.2 million in the fourth quarter of 2019 compared with the fourth quarter of 2018. A temporary deviation from Idaho Power's substantive postretirement plan resulted in a $4.2 million charge in the fourth quarter of 2018 that did not recur in the fourth quarter of 2019. An increase in income from Idaho Power's unconsolidated investment in Bridger Coal Company (BCC) increased non-operating income by $2.6 million in the fourth quarter of 2019 compared with the fourth quarter of 2018, due to lower sales prices at BCC in the fourth quarter of 2018. Also, interest expense on long-term debt was $1.5 million lower during the fourth quarter of 2019 when compared with the fourth quarter of 2018, due to the repurchase and remarketing of the pollution control revenue bonds that was completed in the third quarter of 2019. Finally, allowance for equity funds used during construction increased $1.0 million in the fourth quarter of 2019 as the average construction work in progress balance was higher throughout the quarter compared with the fourth quarter of 2018.

Income tax expense was $2.3 million lower during the fourth quarter of 2019 when compared with the fourth quarter of 2018. Amortization of vintage investment tax credits that became available in 2019 lowered income tax expense by $3.4 million, most of which is not expected to recur. This tax benefit was partially offset by higher pre-tax net income in the fourth quarter of 2019.

At IDACORP Financial Services, Inc. (IFS), a $3.0 million increase in distributions from the sale of low-income housing properties led to higher IFS net income in the fourth quarter of 2019 compared with the fourth quarter of 2018.

Net Income – Full-Year 2019

IDACORP's net income increased $6.1 million for 2019 compared with 2018, primarily due to higher net income at Idaho Power and IFS.

Idaho Power's customer growth of 2.5 percent added $18.8 million to Idaho Power's operating income compared with 2018. Lower sales volumes on a per-customer basis decreased operating income by $21.4 million in 2019 compared with 2018, primarily due to lower irrigation sales. Greater precipitation and more moderate spring and summer temperatures in Idaho Power's service area led agricultural irrigation customers to use 12 percent less energy per customer to operate irrigation pumps during 2019 compared with 2018. To a lesser extent, sales volumes on a per-customer basis in 2019 were negatively affected by lower per-customer commercial and industrial sales.

The net decrease in retail revenues per MWh reduced operating income by $2.8 million in 2019 compared with 2018. As provided by the settlement stipulation approved by the Idaho Public Utilities Commission (IPUC) in 2018 related to income tax reform, retail revenues per MWh in 2019 were reduced by $7.4 million of non-cash accruals for future amortization related to regulatory deferrals that would otherwise be a future liability of Idaho customers, compared with a $1.5 million revenue reduction in 2018. In 2018, a corresponding $4.0 million of non-cash accruals were recorded as other O&M expense for the amortization of specified deferrals. The decrease in retail revenues per MWh from these non-cash accruals was partially offset by changes in the customer sales mix, as volumes sold to residential customers in 2019 made up a greater portion of the customer sales mix compared with 2018. Residential customers generally pay a higher per-MWh rate than other customers.

Other O&M expenses were $8.7 million lower in 2019 compared with 2018, as Idaho Power's continued focus on managing other O&M expenses resulted in lower expenses across a number of areas. Lower bad debt expense reduced other O&M expenses by $1.1 million, due primarily to enhanced collection efforts and a strong economy. Also, other O&M expenses in 2018 included $4.0 million of non-cash amortization expense of regulatory deferrals pursuant to the settlement stipulation approved by the IPUC in 2018 related to income tax reform.

Based on its 2019 Idaho ROE, Idaho Power recorded no additional ADITC amortization or provision against current revenues for sharing of earnings with customers in 2019 under the Idaho regulatory settlement stipulation approved in October 2014. In 2018, Idaho Power recorded a $5.0 million provision against revenues for sharing of earnings with customers.

Non-operating income and expenses, net, increased $9.9 million in 2019 compared with 2018. A temporary deviation from an Idaho Power substantive postretirement plan resulted in a $4.2 million charge in 2018 that did not recur in 2019. Allowance for equity funds used during construction increased $2.8 million in 2019 as the average construction work in progress balance was higher throughout 2019 compared with 2018. Also, investment income from the Rabbi trust associated with Idaho Power's nonqualified defined benefit pension plans increased $2.2 million based on stronger asset returns in 2019 compared with 2018.

During 2018, Idaho Power recorded tax benefits for a $5.7 million remeasurement of deferred taxes resulting from income tax reform and $1.3 million for tax-deductible bond redemption costs incurred in 2018. There was no such remeasurement or bond redemption in 2019. These items, combined with higher pre-tax net income in 2019, resulted in higher income tax expense in 2019 compared with 2018. Amortization of vintage investment tax credits that became available in 2019 lowered income tax expense by $3.4 million, most of which is not expected to recur.

At IFS, a $3.0 million increase in distributions from the sale of low-income housing properties led to higher IFS net income in 2019 compared with 2018.
